Solifenacin is a medicine prescribed by doctors to treat overactive bladder. To ensure effective treatment, patients need to take medicine according to prescription or under the guidance of a doctor or pharmacist.
1. How does Solifenacin work?
Solifenacin, commonly known as Vesicare, is an anticholinergic drug used to treat overactive bladder. It helps to increase urine retention in the bladder, thereby helping to treat urge incontinence (urinary incontinence) or urinary frequency and urgency.

When visiting the doctor, the patient should inform the doctor if there are problems such as difficulty urinating, urinary retention, severe gastrointestinal obstruction (toxic megacolon), myasthenia gravis, decreased bowel movements, glaucoma, impaired vision (glaucoma), liver or kidney disease, gastroesophageal reflux disease, autonomic neuropathy or a history of hypersensitivity to solifenacin or any of the excipients. If one of these cases is encountered, caution should be exercised when using Solifenacin .
In addition, the patient also needs to list to the treating doctor any drugs currently or recently taken to avoid adverse interactions such as:
Drugs with anticholinergic effects (increased effects and risks) chance of experiencing side effects); Cholinergic-enhancing drugs (decreased/disappeared of Solifenacin); Drugs that stimulate gastrointestinal motility (such as metoclopramide, cisapride by reducing the effect of these drugs); Anti-osteoporosis drugs (bisphosphonates due to their increased risk of esophagitis); Antifungal drugs (ketoconazole, itraconazole reduce the elimination of solifenacin); Antiretroviral drugs (ritonavir, nelfinavir reduce elimination of solifenacin); Antiarrhythmic drugs (verapamil, diltiazem reduce elimination of solifenacin); Anti-tuberculosis drugs (rifampicin, increased elimination of solifenacin); Antiepileptic drugs (carbamazepine, phenytoin, reduced elimination of solifenacin) Increasing or decreasing the excretion of Solifenacin both alters blood levels of the drug leading to changes in its effectiveness and potential for adverse effects.
